I'm hoping they arrive sooner rather than later because they don't want interaction with my cat (my cat is also likely to just hide from people who aren't me, but she's cut off from the room she spends the most time in until that's done so I don't have to chase her down if she decides to be uncooperative later)

Pro tip: don't vote for right on time/early - The start of the window has passed and they're not here, so it's no longer possible for that poll option to be right in this timeline.

Looks like the correct answer is First half. If you want to cheat, now is the time to answer the poll. They're not sure if they'll be able to fix it, but they're going to give it a try.
